Thanks for digging that up, but he didn't specifically address Is There Anything About.
Over time the "two bands" legend for Product (and onward) seems to have evolved somewhat. I seem to recall it being described as a schism between two factions, but now it seems to be portrayed as the band splitting into two working groups, one which kept going in traditional Brand X fashion and the other tried to deliver something that was in accordance with record company demands that they take things in a more pop direction. The former scenario made it seem like the old standard sitcom trope was in effect, or something.
